Learning portal with an interactive FBD simulator
Learning materials, practical tasks, and an interactive FBD simulator for studying logic diagrams, PLCs, and industrial automation.
Two learning tracks
The site sections help users study Boolean algebra and the basics of PLC programming. Create your own logic diagrams or use ready-made examples.
A section about describing a circuit's operating conditions through logical values and operations. You will learn when a variable is considered TRUE or FALSE, how to combine conditions with AND, OR, NOT, and XOR, and how to check the result using truth tables.
Industrial automation practice: inputs, outputs, scan cycle, function blocks, memory, timers, and counters.
From logic to PLC
Boolean logic describes conditions. A PLC uses those conditions to control real inputs, outputs, sensors, and mechanisms. FBD represents that logic as a visual diagram.
Study the rule or block behavior.
Open a commented training diagram.
Toggle inputs and observe the output.
Change the condition or add a block yourself.
Program examples
The catalog includes simple logic tasks and practical PLC diagrams. Each example can be opened in the editor and checked in simulation.
